The Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel was first awarded in 1969. Since then, 78 people have won the award, and of these, 82 percent of them have been from either the US or the UK.

However, this trend is not isolated to the economics prize — it extends to all other science awards — medicine, physics, and chemistry.

The western world has dominated the awards for the entirety of its existence, with the US in first place with 367 laureates.

The UK trails behind in the distance with 125 laureates and Germany comes in third with 105.

Why is the US so far ahead?

The number of Nobel prizes won by the US began to climb shortly after World War II.

According to Stuart Anderson, executive director of National Foundation for American Policy, this coincides with the passing of the Immigration and Nationality Act of 1965, which removed the county’s national origin quotas and opened the door to Asian immigrants and the later Immigration Act of 1990 which led to greater numbers of employment-based green cards.

These two movements made it significantly easier for the US to bring in talented, intelligent people from all over the world.

In 2016 all six of the US Nobel laureates were immigrants.

Between 1901 and 1959, 25 immigrants were awarded Nobel prizes in chemistry, physics and medicine, whereas between 1960 and 2016, seventy-nine immigrants won Nobel prizes in chemistry, physics and medicine, more than triple the original figure.

However, this success is not a story of immigration alone.

The US has a history of awarding generous research to grants and has better access to higher education than many other countries. The US is also home to some of the world’s most top universities and they spend more than any other country on scientific research.

Many scientists come to the US because of its research friendly funding system.

Fraser Stoddart, a Scottish Nobel laureate, said:

Science is a global pursuit, it must allow people to come and go across different cultures from different countries. It’s not about money, it’s about people. Diversity really does enrich the process of discovery and invention.

Richard Dawkins, in 2013, tweeted that all of the world’s Muslim population had fewer Nobel prizes than Trinity College, Cambridge. The same applies to the whole of China and the whole of the female gender.

However, when sorted per capita the US drops to 15th in the global table, while the UK falls to 9th.
